I am working on three bikes. Rt1, Ct1, and Jt1. I want to get the oil injection working. Could some one lead me to a good how to on the subject. I know Deet will rebuild the pump can't afford $300 right now. Is this something a do it your selfer can do? Was thinking of tearing into one and trying my luck.

I'm not sure it's something you can DIY. With something that important and vital to your bike I would have a professional do it. My suggestion would be to send in one pump at a time while you can afford it. I sent him my pump the same day I found out my dog needed a $1200 surgery but it was to late I shipped it out already so I feel your pain

If you are a decent mechanic, with a careful and methodical approach, you CAN rebuild these yourself. I have had DEET do the last couple of mine after I screwed one up though. There are several really small parts inside, and like the steering head balls, they have minds of their own.

You can get a seal kit from HVC Cycle HERE: hvccycle.net/yamaha-oil-injection-pump-re-seal-kit-hvc200103/

Read the copy as there apparently are a couple of sizes?



You might try finding another used one and carefully disassemble so if it goes sideways, you can learn along the way. Keep DEET's address handy though . . .

+ 100 on using DEET...

Tip: If you decide to do it yourself there are some tiny spring loaded pieces inside the gear... I saw it recommended that you disassemble inside a clear plastic bag as if those parts accidentally fly out you're likely to never find them again... Aircooled RD Club forum used to have a really good step by step with pictures but I think it is gone after a forum crash.

yes there's a couple of tiny plungers & springs in there & if they pinged off without see them go then the pump would be wheel spinning & pumping nothing. If money is a bit tight why not just bleed them up to make sure they're working & just carry on till things improve. I sold a new pump a while ago for about $60, now i wish i'd kept it damn it.
