Yea I bought another of the same chain because I'm pretty sure this one is defective some how. I'll try calling RK tomorrow but I doubt they will do anything.Julien D wrote:Those cheap RK chains last me about 2 years. I like them fine, and don't mind replacing the chain and sprockets every other year.
I could have just got it running and ran with it but I knew if I did that I would end up never fixing the cosmetics. I'd rather make it look nice all at once and then maybe touch up areas when they get messed up. Probably wont even do that though haha.Julien D wrote:Bike is looking great. I'm glad you've taken the time to fix her up as nice as you could. This is pretty much the way I built my 89. Money was tight, I did the minimum to get riding, and continued working on it and tweaking it as I could.
Yea after playing with it more today, it pulls great rolling up to WFO, and even snapping it open from 1/2 throttle or so. Just bogs snapping from 1/4 to full.Julien D wrote:As far as the jetting, the issue lies in the design. You have a carb with 3 circuits, and an ICS engine with a nearly 10,000 rpm operating range. It is not possible for the fuel to be metered perfectly for 3,000 rpm 1/4 throttle and 3,000 rpm WFO simultaneously. If you get it rich enough to eliminate that bog when you just crack the throttle open from idle speed, it's going to be much to rich to pull cleanly up top. There is always going to be some measure of "rolling on" the throttle with a carbureted two stroke to maximize acceleration. If the bog is very noticeable, then yeah, you probably need to keep tweaking the jetting. You should be able to get it to a point where you wouldn't ever notice it unless you were trying to.
I also noticed that if I pull the choke, it will snap hard like that, but won't really rev out properly.
I just need to stop screwing with it and do the plug chop. I know a little about jetting but I am not near familiar enough with this bike to be judging jetting off of just feel.
PS: I really need to get this thing finished so I stop testing it in the back yard. It's addictive and there are going to be berms soon if I don't cut it out
