Well, my problem finally showed it self. My exhaust port doesn't want to meet up with the cylinder port! No matter how much I fiddled with it. Pretty upsetting not to be able to have something for you guys. I'm gonna play around with it tmr and compare the cylinders. This kit seems to sit a couple mm's closer to the crankcase than the other kit. As in, the stud bolts are showing more through the cyl head than they were showing on the stock head. I'll take a look at some brackets that others have made. I don't think I'll make it myself but I'm gonna try and figure out/steal someone's design for this one. We'all see if I get anywhere tmr      could you share the link to the cylinder you ordered? There might be clues to the exhaust ports configuration and why the flange doesnt meet. Also, what make model and year scoot do you have? I'll dig around tomorrow and see if i cant find something out |

I find it strange that it sits father down. I'm gonna take it apart and compare the kits in the morning. The link is scootertuning.ca/en/cylinders/67001-cylinder-motoforce-sport-70cc-cpi-vento-12mm.htmlMy scooter is a 09 keeway hurricane. Ill make sure to post anything up I find right away! Thank you! |

We'all see if I get anywhere tmr That looks pretty far off, but I'd still try to attach it to the cylinder first (loosely) and see if you can finagle the other end into position. Myself, I always attach the flange first. If it takes pressure to mount the other end, then don't do it because you might end up breaking something. |

Yes I fiddle with it for quite awhile maybe 20 minutes just huffing and sighing lol it seems to wanna sit pretty far off from the bolts near the flywheel when I place the "flange" into position first. I thought about attaching the bolts but it's just to far. I took the picture with the bolts (loosely)holding up the exhaust. That's the closest I can get from there.  Tear in eye. |

That bites. Silly question maybe, but I've never messed with the clones and so I don't know, but wouldn't you want a cylinder for a Jog or Zuma? I thought you had a Minarelli clone? Again, I've never messed with one of those motors so tell me to shut up if I don't know what I'm talking about  |

Again, I've never messed with one of those motors so tell me to shut up if I don't know what I'm talking about Yes mine is the clone. But the site dooes say it fits my keeway? Lol the jog and zuma gives me same results for cylinders besides mine is a 12mm. And no worries on the cylinder, I'll get it sorted out. Might need to get a friend to help figure it out. |

Oh right, it's the 12mm pin that makes it different. I get it now. I'm sure that you will figure it out, and having a second set of eyes look something over sometimes makes a difference. |

It's common to need to enlarge the holes in the exhaust mounting bracket to get pipes to fit. I'm not sure if I have a pipe around that I haven't altered the bracket on in some way. If it's so far off that the holes can't even align with the bracket at all, then there's a different issue.
Doesn't sound like it's the problem here, but some of these engines have a little bump cast into them on the bottom and pipes that hug the case will need that bump to be removed. I chop 'em off with a sawzall I've only ever seen that with my Phongeer exhaust, but thought I'd mention just in case.

Sadly some kits are like that. The S6 Streetrace cast kit is the same way, I had to fabricate a bracket for mine. I never noticed it before now but in the picture they have on the website you can actually see the difference in angle on the exhaust flange for that kit compared to something like the DR cylinder. I have used a DR cylinder on a zuma and it fit like a glove.

Thanks guys! Glad to have some opinions out there. I am considering sending my scoot to a friends, completely and get him to put the pipe on. That's a last resort tho. Does anyone find it odd that the new cylinder seems smaller than my stock? And yes you can see in the pictures that the exhaust intake is shorter on the big bore than it is on the stock it's like waaay smaller. I didn't really take a minute to compare the cylinders , but i was looking at the picture I took right after I got the stock cylinder off.  I guess this is where that tantrum starts, that I so often hear about lol. This ones gonna drive me nuts. I don't wanna ruin my exhaust, but spaz did say get a bigger hammer! Hehee, has someone taken a hammer to the exhaust before to get it nudged into place? Also, if I saw/grind down the protruding holes of the exhaust bracket bolts, and somewhere down the line I get a performance pipe, how would I get around this? I assume buying a pipe won't solve my problem humm dee humm , I'm taking that cylinder off right now!!! |

Angle grinder is offically out. I think what Brent mentioned about sawing those bumps down may solve my issue....we shall find Out! But don't get your hopes up yet! The bolt holes seem to "line" up but they just don't meet. I think the bottom bolt on the bracket need to be sawed a little to push the flange upwards. I'm sure that makes sense to those of you who've made there own brackets. I'm honestly so thankful for having such helpful aaaaaand such patient people here. Really glad too you haven't given up on me! Update in a bit. 49cc..... hhaaaaaa (sound of heavens)  |

Ive built several pipes that fit my stuff perfect and shipped them only to find it wouldnt line up!Its always the cylinder flange,,located differently enough to make us mad,,seems like the "industry standard" is lacking here..As others have said to bolt it to the cylinder then make the rear bracket on the muffler fit which may involve sawing off the ears on the muffler and making new ones to line up with the engine brackets.If you could bolt it to the flange and take a pic of the rear mount,perhaps we could come up with a hardware store fix without breaking out the welding equipment..
PS,Please dont try to 'force' anything into alignment!!

PS,Please dont try to 'force' anything into alignment!! DOnt worry I'm not the forcing type lol. I'm scared of breaking anything. But when you guys say "ears" what exactly are you talking about? Like on the bracket? Or the ears on the flange? I, myself don't know how to weld, but my hubby does.(I've always wanted to learn btw) the end of my pliers are pointing to where IM talking about when you say ears. Let me take a picture/probably a video since my ipads so big and annoying, of the flange attached to cylinder and showing the rear bracket.  |
