KidKart Comer Engine

Dear Lyle,

The engine 885 is doing well and we are still racing it at the present time. We are leaving to race in the ASEAN series next week and the race will be in Jakarta. Bryan has been doing reasonably well this season with either a second or third in every race but still without an outright win in the final. A couple of poles and some heat wins with the engine.

I believe that the cryo treatment on the cylinder liner helped and we are still using the liner with more than 80hours of racing and practising on it. These cylinders are rated to 60 hrs and usually are changed at around 50 when we race, so that is a great help. We do not fit a temp guage to our enigne and cannot tell you if the engine run cooler but a "seat of the pants" guess would tell me that it is running slightly cooler as we seem to be getting more consistency towards the end of the race when in the past there was a slight drop in power as the engine heated up.

The major difference is in the treatment you did on the clutch. Since fitting it, we have not had to change it at all and it seems to provide better bite coming out of the slower corners. We are extremely pleased with the results in this area. Bearing life on the treated items are also longer which is a bonus with fewer rebuilds.

I will be sending some more items to you shortly for treatment but am expecting a friend from Chicago coming down in September and will wait for him to be my courier and save some moolah.

Thank you for asking and overall I do believe that it was money and time well spent.

I hope that you are well and will look forward to hearing from you in the near future.

Best Regards,

Mike
