I've already replaced both of the bearings because the front one was leaking, and changed the carb. because i thought that was causing the issues.
Tried a lot of different exhausts and different gear ratios but just no power.
When i tune it to get some performance out of it it runs on 180 celsius.
And JP won't take it back, while there is simply something wrong with it.
Too bad for a 420 euro engine, next engine will be a RB. I'm done with the terrible service (no service) from JP.
This is interesting. I have a Eagle TL-3. I carefully broke-in the motor on a bench, ran it very rich on a track for 2 days to finish break-in, replaced the conrod, raced it one day still a little rich, then I went to the capital classic. I ran it wed, thurs, we had rain friday so saturday was 3 qualifiers then sunday was the mains. I never leaned the motor more than what was needed to make 5 min. It never got above 270F. I was about 15 min. into my main when the rod broke. It broke at a slow part of the track and it actually twisted then snapped. I sent JP an email explaining everything and told them I had pictures I could send also. They weren't interested in my pictures and said that it must of been something I did. Now, I understand that there are no warrenties with this stuff but I've had other problems in the past and other companies were willing to help and were concerned about keeping me as a customer. Not JP. They don't believe in "The customer is always right." They believe "Our engines are perfect. If it broke, it was your fault."
But the good news is that Joaquin Desoto is taking care of me. He actually cares about if I buy another JP engine. If you buy all your JP stuff from Joaquin, he will take care of you.
