Hi mates, I had a worn out CY 26cc and decided to install the Rovan 4bolt 30.5cc +2mm upgrade kit. Myself, My brother and my dad have the Dominator pipe on our HPI Bajas. The strange thing is that their CY26 is pulling wheelies and seems to have more power, and my 30.5 seems to be underpowered at the launching stage, and not revving as high. There seems to be some short juicy power only at the mid revs. We all have the WT668B, same gearing, same tires, same fuel, same dominator and same 8k clutch. Their launching is hard and sounds aggressive. Mine launches underpowered and opens up in the mid revs, but still not faster then theirs.
The engine is on 2nd tank ...I have no leaks, good compression, white spark, new NGK plug.
Do you have any ideas what this could be? I am frustrated! I pretend to have more power due to the larger bore and longer stroke! Thanks in Advance
I would really appreciate if you hint me up!
