SYM HLEP!!!!

[camogy6]

Here we go again. 

Our other Mechanic at the shop got a great deal on a Lance PCH50 that we took back in on trade not too long ago. We are a SYM/Lance Authorized Dealer. I know SYM makes a bbk for their engines, but they have not been the greatest help out there. They either don't have them stocked, or some other excuse. 
Anyway, I'm looking for a quality BBK for this 1P37QMB motor, and have hit a few misunderstandings. The Mio motor is different from the rest and of coarse there is plenty of stuff on the market for that motor. I have heard a few places that the blocks are the same and you can bolt a GY6 bbk to that block and it is the same. Now, upon inspection, the heads are obviously different, but the rest doesn't look that far off. 
Anyone know if this is true?
Anyone know where i can find bbk parts for Lance/SYM 137QMB Engines??

Hope everyone is well,
PAT

I've always had good luck with NCYs BBKs. I think they make one for a 1p37qmb. If you only go to 47mm bore the stock head ought to work.

I too myself have a Lance Cabo 50 1p37qmb engine. What I do know for sure is that Naraku makes 42mm cylinder for sym/lance which is 63cc from 50cc. Also is true with this you can still use your stock head and rocker arms.

However you can go to all other sym/lance BBK Options as long as you have 139qmb cylinder head to do all your upgrade needs. I'm just not to sure about NCY having 1p37qmb parts actually im pretty positive they don't. I've only came across Naraku which I'm becoming a fan of, but than again when its the only BBK option you have I guess that makes you a fan
