Useful Strip down photos for a VTR Firestorm
29 Attachment(s)
Decided to strip the bike to check the valve clearances on the rear cylinder, main reason was to cure a slight oil leak on the APE CCT. Here are some photos of the job. Note this is a 2002 F2 model with the 19l tank. You will see there is no tap so I had to be a little adaptive.
Attachment 25640 Disconnecting fuel sender unit Attachment 25641 Loosening pivot bolt at the rear of the tank Attachment 25642 Removing front bolts Attachment 25643 Support the tank using a piece of ply, note I use the tank bolts as added slippage protection Attachment 25644 View under the tank note 2002 model and no shutoff valve. Adapted tool to clamp off the fuel line. Note, have as little fuel as possible in the tank. I had 1 bar on the fuel gauge Attachment 25645 Fuel line clamped off. Note the square rubber tank protector (one on each side) in the foreground of the above photo can fall off, don't loose them. Next follow the main fuel delivery line from the left of the clamping device round to the fuel vacum assembly. Unscrew the fuel line clamp & pull off the fuel hose, there will be a little fuel spillage so have a rag at the ready. Then pull off the vacum & overflow pipes from the bottom of the tank. Those are the 2 pipes still attached to the tank avove the clamping device in the above photo. Note, I have alread removed the nut at the end of the pivot bolt ready for tank removal. Support the tank, remove the pivot bolt , and lift away. Place the tank somewhere safe & I plugged the fuel delivery pipe using a 12mm bolt wrapped with some PTFE tape, this allowed me to remove the clamping device so as not to damage the pipe any further. Attachment 25646 Photo of the tank removed showing the vacum assembly including both main carb fuel feed pipes and the small vacum control pipe. Attachment 25647 Airbox lid removed showing air filter. Note you can remove this lid & change the air filter without removing the fuel tank by having it pivoted virtically as shown earlier, please have an assistant available to support the tank as you remove the airbox lid just in case. Attachment 25648 Air filter removed showing trumpets. Note: long trumpet at the rear & small at the front they are arrowed to the airbox housing as to correct orientation. Trumpets removed & carb mouths secured against foreign bodies falling in. Attachment 25649 Airbox housing is secured with 8 bolts which are thread locked in. These have now been removed. Now comes the plumping bit. The following are photos of various pipes that need to be removed that can be done in any order. Accessability & small hands are an advantage here. Attachment 25650 Attachment 25651 Attachment 25652 Attachment 25653 Finally :D Attachment 25654 Attachment 25655 Airbox off. Next up is to remove the fuel vacum assembly Attachment 25656 Attachment 25657 No need to remove all the fuel lines I supported it with a shoe lace attached to the wing mirror Attachment 25658 The next sequence of photos is an aid to ensure you remove parts in a particular order so as to repeat in the re-assembly process Attachment 25659 Remove rubber protector Attachment 25660 Attachment 25661 Disconnect & remove rear cylinder pair valve pipe. Attachment 25662 Now you have reached the rear cylinder rocker cover. Before removing first remove the altenator center plug. (AS STATED IN OTHER THREADS THIS IS MADE FROM A VERY SOFT ALLU & CAN BE A SOD :Argue 1: ) I tapped mine back & forth & it eventually gave way. You may want a spare ready just in case you need to bastardise it off. When replacing it use some grease on the threads this will help removal next time round. Then remove the timing access plug to the left of the center plug. NOW REMOVE THE SPARK PLUGS FOR BOTH CYLINDERS & COVER EXPOSED HOLES. Attachment 25663 Attachment 25664 Next remove the 4 rockercover retaining bolts Attachment 25665 Note: the orientation of the washers the way UP is clearly stated on them. I also smear them with engine oil when replaced. Next you need to find TDC for the REAR cylinder please refer to the CCT thread for this proceedure. Below are photos of what TDC looks like for the REAR cylinder looking at the cam lobes/sprockets & timing window. Note (ALWAYS TURN THE MOTOR COUNTER CLOCKWISE USING A 17MM SOCKET ON THE BOLT IN THE CENTER OF THE ALTENATOR HOUSING). Attachment 25666 Attachment 25667 Attachment 25668 Reassembly is the reverse of what you have seen. This is as far as I went. My valve clearences are a shade on the tight side but have been reliably informed that they can wait for the the next workshop. I also stopped the leak on my APE CCT. I hope this will help some of you out there I do like photos as they speak a thousand words. Happy spanners :thumbup: Note I had to remove 7 photos from this post due to the 30 limit i believe the essence has not been lost. |
Hey great write up, great pics, there should be a database on the forum to look this stuff up, would be useful. I kinda wish I woulda done this on my recent motor swap.
|
Well you have shown me some creativity (with the make-shift ,fuel clamps) and I am in agreeance with Smokin'Joe. I am just starting a from the frame build up(A real BASKET case- Superhawk) and you have shown me a reference to how to photo the process...
By the way- Not meaning to be nosey.. The propane heater in your photo- How well , or efficient are those heaters??? |
Bump.
Nice photos of what to do/look for when getting to valves. Mahalo. |
So the tank you have with the different petcock location is the larger one or the smaller one?
|
I have a '98. I believe all the U.S. models were the same size(19l). On my tank the petcock is attatched to the tank with the on/off valve. Still great photos of what its like under the tank/ valve covers, for those who have not ventured that far yet.:)
|
It would be much easier to just unbolt the petcock from the frame, than clamping the tube... That's just making things more complicated than they have to be...
With the petcock unbolted, you just unhook the carb feed lines and vacuum lines and let it follow the tank... That's the same as you do on the older bikes where the petcock is attached to the tank... Nice reference images though... |

YOU ARE WRONG!!!!! Can't say it in a nicer way, sorry... And it keeps confusing the issue further when people do searches and find X amount of posts like yours with "beliefs"... The US bikes all have a 16L tank, not one of them was ever delivered from the factory with a 19L tank... Not a single one... You can either trust me on that, or find out for your self... In Europe and Canada, as well as the rest of the world, in 01 the tank was upgraded to a 19L tank, and the petcock was moved to the frame to make room for the extra volume... For whatever reason I dunno, but I guess to keep parts similar, Honda decided to make that same change in the US bikes, even if they kept the 16L tank... Darkember is UK based, so he does indeed have the 19L tank... |
So today when adjusting my CCT on the front I believe it jumped 3 teeth based on the 3 clicks I heard...
Do both cams have identical markings to indicate where TDC is on each? I see your closeup of the right cam, but I don't see the left one. |
the front markings are FE and FI
FE is the left side cam FI is the right side cam make sure the crankshaft marking is on the FT marking this should get you back in timing |

Basically how to I know if I am timed correctly or need to rotate one or the other based on the one that is always correct at TDC. |
O.K. Tweety, didn't mean to cause confusion. Didn't catch his location. Just wanted to repost the pictorial part of the undersides. I did realize that his was a '02. Though even if it was the a newer/ non-U.S model, it did help me before, in getting an idea of the various hook-ups and locations of parts. I thought that it might also help those searching and certainly did not mean to confuse anyone. I was not definetly sure so I did not want to say so. Comment well taken:), will try to be more careful next time.
I certainly do not question your knowledge base.:) |

**Just a note to correct my previous post(#6) without losing the context of the thread.**
As pointed out by a very well knowledged member, the fuel tank size on my U.S. model tank is 16L(4.23 gals), NOT 19L. Sorry for the confusion. (Thanks Tweedy). (Maybe I was wishing too hard that I did have the larger non-U.S. tank :). ) |
knickers in bunch.
|
Thanks tweety. I seem to recall seeing something saying that all the US models had the larger tank which I thought was 19L and then when he said he had the 19L tank with the different petcock I was a bit confused. What's the best way for someone in the US to acquire the 19L? Are there sites like Craigslist or other calssifides over there that a guy could look at?
|
Thanks for the pics.. Now I know how to get to my spark plug lol
|
Never saw this post, so took the time to read it.
Now, this is the fun part for me. I get to correct Tweety on misinformation about the tank size. No, Canada never got the 19L gas tank...;O) |
Firestorm and Superhawks are a little different. My Superhawk has the petcock attached the to the tank... other than that the pictures helped me a lot thanks..
