Jetting need help

[Merlin]

Hey there all,

I just installed a rm timing plate and adjusted it to +4. The bike ran like crap. (backfire, sputter etc.)

So i put it back to ) degrees and it still ran like crap. I put in a new set of plugs and ran it wot from 1-4 and shut it off. The tops where a light gray, maybe even whitish which is lean.

 

The problem is, before I installed the timing plate it was working great.

I believe its either a bad timing plate, possibly my staor went while I was doing this or I may just need to rejet.

 

If I rejet, what should I go with??

The bike has 125 psi in each cylinder, fmf fatties w powercore 2 silencers, K&N filter and K&N lid.

 

I drive most of the time at less than 500 ft, and the temp range from 20F - 90 F.

 

Any help wuold be great?

125 psi in each cylinder

 

That's a part of the problem.

125 psi per cylinder is not "part of the problem." 125 is fine, unless you have a modified or aftermarket head. I would guess you didn't get something installed correctly. Pull the flywheel back off, and make sure the plate is installed nice and snug (3 bolts). Make sure you didnt lose the key on the end of the crankshaft, and the spline in the flywheel is sliding on the key correctly. Finally, check the gap from the pickup to the tabs on the flywheel.
