Rebuild a neglected one


Picked up this 98 w/ 26k miles. It has tags from 2013 so it been a minute since it's seen the road. Just started to clean her up and tear her down. She turns over but the entire fuel system needs a rebuild, carb slides don't move, tank has rust and hoses are as super stiff. Trying to get the carbs off at the moment but they are currently stuck on those dang intake boots.Anything in particular I should be on the lookout while I'm rebuilding her?

An undamaged, unmolested example! Good find. Shame about rust in the tank. Probably the toughest problem to get right. Consider fuel filters after you get the tank sorted.
Yup, ~25 year old rubber and plastic, especially in Phoenix is going to need attention.
If you rebuild the carbs yourself, the jets are different front and rear. Don't mix them up. Be very careful with the plastic fittings that are part of the enrichment circuit. Easily broken. There are brass replacements available, but not so simple to source. The vacuum operated petcock can cause issues with fuel delivery. Pay attention to where the lines connect to it.
Tip of the iceberg.

Thanks Xeris, I'm definitely going to be paying attention while breaking these things down and documenting jets and settings. Are these plastic elbows the one you're talking about? Both sides look like this.


Would you recommend rebuilding the stock petcock or getting a non vacuum replacement.

Yes, those are the elbows. Use honda parts when ever possible.

Wow, Nice find!
My only definite add would be installing MCCT's and the R&R upgrade.
Otherwise, all the norms: brake fluid, coolant, oil.

Thanks ZKarma, I'm pretty excited. Any recommendations of brands for the MCCT's? My search on eBay seems to bring up a lot of the same looking non branded types.

I went with these ones from blackpathracing, but I'm sure many of the Ebay ones come from the same overseas factory.
I seem to remember going with this one, thinking the O-ring providing an additional level of sealing, but then just had the afterthought
(4yrs later) that o-ring isn't sealing diddly squat on those course threads, lol

MCCT's are a must! Check out Kreigers.

If it sat for that long, I'd consider a full rebuild and meticulous clean of the clutch master and slave cylinders. The slaves get nasty of ignored.

I have heard of the MCCTs (manual cam chain tensioners), but R&R? "Rest & Relaxation" comes to mind😁. Thanks.
