Hello all! I have an '89 "R" that I absolutely love. I've done a lot of things to it and I have learned a lot, but recently it's top end power left all of a sudden, like the flip of a switch and I'm not sure what to check next. Here's what I have and what I've done:
CT Racing 350PV cylinder, 39mm carb, K & N, Lightened flywheel, Cascade silencer (head pipe is fat, but I don't know the make), Ricky Stator high output, trail-tech lights, stock cdi, coil, rectifier, run/stop/light switch and stock timing.
So when it acted up, I noticed that the rear tail light "flickered" constantly regardless of where the light switch was set and the front lights didn't work at all. Assuming the problem was electrical, I replaced the cdi with a new OEM as I've had problems with them before. No change. I'm wondering if perhaps my "high output" stator could have damaged my start/stop/light switch??? It is less than a year old and OEM as well, but I don't want to buy another just to find out that it's something else. The entire electrical system is fresh as it was replaced when I had my previous cdi issues last summer.
I've got less than 10 hours on a fresh top end that ran rediculously good.....so I haven't dug into mechanical items yet. I'm still holding onto hope that it's electrical. What should my compression be? It's got the "stock" CT350PV dome and gaskets. I'm assuming that's the first thing to check mechanically. I've read that a cracked balancer bearing, spun crank bearing, or cracked flywheel could throw the timing off at higher rms's also....say it ain't so! It does start and run at lower rpm's well, just not nearly the same arm ripping powerband it had before. Any words of wisdom from you pros out there would be greatly appreciated.
