Yeah I am at a loss myself here like I said I am getting tired of laying on my back in the garage but again I don't want to leave t anywhere so I am left with no choice but to do if again on the floor .I'm stumped buddy. I'd suggest checking everything you just mentioned.
i had to pull my tranny out a couple times,i can do it in no time now...lol,i was amazed how much a unbalanced flywheel made the engine vibrate!,but car purrs like a kitten now...So I am still chasing the vibration here . I have narrowed it down to an engine vibration .
Down shift crusing 3k rpm keep Rpms up and slow the car down vibration feels the same so that rules drive line out .
I shouldn't have been so quick to blame it on the TRANS even with that input shaft play . I was foolish and should've pulled the bell instead of just inspecting .
My next thoughts are the dowel pins are worn on the PP causing it to dance at high rpm but again the bolts should hold it in place . or the fly wheel bolts are slightly backed out . Or the motor is f u c k e d .
So I have about 2,5 weeks to get my ass In gear and pull the TRANS again and get it all sorted out before American muscle show in PA . again I feel it has to be some error on my part during the install as it didn't have this vibe until we tuned it . Ah the joys of trying to go fast !
oh I can do it in 25 mins on my back it's going back in when I am cursing . I built this whole car in here remember so pulling the motor and everything is like oh ok we gotta do brakes today kind of thing I just don't want to have to go that fari had to pull my tranny out a couple times,i can do it in no time now...lol,i was amazed how much a unbalanced flywheel made the engine vibrate!,but car purrs like a kitten now...
I always say I will get a quad when I get old! LOL. I love motocross and riding. Kawasaki is bar none the fastest. Suzuki is the best handling, Honda is down right reliable with manageable power (some say slow). Yz is good all around. Ktm is European and parts can be hard to find and $$$.I'm actually Looking at buying a 450r or a yzf450 this week . I have rode quads since I am 11 and never owned my own and I wan one
Did d/s today and it deffinitley drives smoother so I am sure those universals in that drive shaft are junk . but the vibration is there. I am gonna prob pull TRANS tomorrow and check it all out I did doubles back to back last two days so it's time for bed !
Alright so its all together , No more vibration until 4k. 4k up into 5k and it kind of smooths out again. It drives like it did before we had the issue when i woulnt put it in boost before it was tuned no vibrations on the low end car drives smooth. At about 1050-1100 if you are stopped right before the idle settles you get a small shake in the wheel like we had but goes away as soon as the idle settles.
Ill put it this way its much better that i am not scared to drive it any more. My next move is to swap the motor mounts out . It has 50 resto cheapy poly mounts in it and maybe try a rubber mount and see how it is .
