I can asure you that Im satisfied. and as for all the different Manu's these kits are far from the same Ive dine the measurements on BGF, CJR, PK, GB and others the only one I found close to any of the other Manu's was the Speedster 60cc'er was close to a 55 hopped up but has wahat appeared to be A Bigger heavier crank. Thier cranks are fairly balnced from the factory a little lighter than some of the 74cc when comparing the 70cc Tiger so the engine characteristic felt more Like the 2 stroke elsinores. Ive cracked the cases!
