Hi all, i've seen the 146cc bore kits for the jailing 124cc engines but i'd be interested if anyone also sells a stroker crank as well????, be good to use the bore kit and stroker crank together.

Akunar has offset pins and parts, and I know a guy who can press it up and true it. Got a 68mm GPX swinger on the bench right now.

A drop-on 57mm 146 jug is the biggest bore without opening the cases. I have seen them be tight in spots and hurt the piston though, so it still needs a little cleanup or at least a careful check. A 68mm stroke has to have the rod ground to clear the trans, a spacer under the jug, and possible camchain issues (we added a 3mm spacer and converted to 14/28 sprockets-it maths out
). A 63mm stroke can use a 97mm rod and stay with the stock jug height, for a no fuss 161cc.

Akunar is a supplier, but not a vendor here.
Yeah thanks! I've just googled them & asked for some prices.
Regards the 6mm stroker crank & 146cc bore kit what size head valves would work best do you think, i've standard jailing 124cc 27/23 valves & the ports have been fully gas flowed, do you know which if any 28/24 valve head & would that be a better idea to let the motor breath better?.

I'm ordering from them late next week, if you want to save on shipping. I haven't seen a Jailing with bigger than 24/21 valves, but done a few Lifan swaps. I'm ordering some 30/26 pairs to turn to 30/24, but 28/24 with good porting will feed it. It's not gonna be a revver, but will have a monster midrange hit.

Crappers, on your own
Can I run this by you, if I use a 55.50 Honda crankshaft with a 2.25mm pin that take's the crank to 60mm, so if I use a 3mm spacer that'll be the equivalent of a 63mm stroker crank? then just change the cam sprockets to 14/28 will this work or have I confused myself again lol. Do you use a stock base gasket either side of the 3mm spacer or just gasket sealant?.

2.25 offset pin? Not at Akunar, for a 55.5 crank. Either Click or Wave pin depending on 25 or 26mm pin.

Is that a whole crank or just the pin and rod kit?
