I was worried about the same thing on my ruckus swap. Do you have a heat gun? I do have a heat gun, but I think I'll have to hack a bit off to get everything to bolt together.  If you can't mod it with a heat gun, maybe just cutting it as little as you can will be enough. You'll have to keep a close watch on CHT at first to be safe either way. I would hate watching the CHT and not knowing whether I'm jetted too lean or that I'm just not getting the airflow I need. On dear. Might end up with a slight stretch after all. This would be worst case scenario! The easyboost dragster mount would give me an extra 8cm, but It would still likely need a bit of trimming on the shroud to completely clear. Don't have that rig but: The hanger bracket, is it two piece's? And is there a chance it could be mounted so the lower portion is be moved to outboard of the frame bracket?  This is what it looks like. The two lowest bolts mount to two pieces welded to the frame for the original mount. re-arranging, if possible, would lose a lot of the strength. |

I need to do a bit of thinking, but I guess I've got a few ways to deal with this. 1.a.Trim the shrouds and see what happens with restricted airflow. 1.b.Buy the easyboost dragster mount. likely still have the trim the shrouds, but have a lot less restriction in airflow. Maybe I should consider trimming the mount? It's 8mm thick, and that's a lots beefier that the original sheet metal used to hold the motor in this bike  2. Abandon the AC cylinder and go LC. I really didn't want to make that jump yet. I love the simplicity of air cooling despite the tradeoff of power. There are so many LC motors around in europe that I thought that the reason I never see any air-cooled horizontal boosters with this mount was because there wasn't any reason not to go ahead and just swap the nitro/aerox motor in. I guess there are other reasons as well. 3. I could just go custom with the mount? I can't weld, but I have friends that can. I wish I could. I'd have a much better idea of scope. I do have an idea of how I'd like to do it. Not as pretty as this one, but maybe along those lines.  |

Shrouds are relatively cheap. You should be able to tell if it’s not cooling well vs tuned lean. If it’s off by far, it’ll run hot even idling. Maybe it’s just me, but that sounds way easier to try than modding brackets, new brackets, LC conversions…

Maybe it’s just me, but that sounds way easier to try than modding brackets, new brackets, LC conversions… I did buy new shrouds for this already and still have the old crusty chewed up one in the parts bin that I can cut up. The reason I'm already thinking about other options is because to even get the other shroud on I had to change from 285mm rear shock to 265mm shock, and it's still very tight in there. An even shorter shock would give me just a little more room, but I don't want it to sit too low. In person, I feel like the blockage is much larger than it looks in the picture. Cutting a section out of the mount would open it up a lot. We'll see how it goes. I'm really close to being able to fire it up. |

Option 3: Sexy AF. That tubular mount looks beefy and reminds me of a ducati. It's good that you have friends that can fab! Option 2: It would really stink to go water cooled after going for a nice ported air cooled setup that is already ready to fire up. There is no question about the cost and added complexity of going water-cooled. I'm holding off as long as I can. Option 1 (a and b): Like Brent said, you'd see it getting hot just idling. I'm not sure if you listed your options in order of cost on purpose but you certainly did  |

Looks plenty strong enough 💪

It looks like maybe putting a little radius into the bottom of the plate might move the yield point a little further back and more towards the center of the plate. Looks like a lot of stress shooting right at a weak point with them bottom line flat. But I'm not an engineer, just my gut feeling looking at it.

What kind of Ignition is that?
great job with the mount it's coming along nicely.

Looks like a lot of stress shooting right at a weak point with them bottom line flat. But I'm not an engineer, just my gut feeling looking at it. I have some gussets that will fill that space in. Although I think the frame would bend before the brackets started to fail. I have a frame brace that will likely go in soon to help with that. What kind of Ignition is that? great job with the mount it's coming along nicely. Thanks! As Lucas said, it's an HPI 2-ten / 210 |

I don't know how to post this, so here goes: I have a 99' Aprilia SR50 (pre ditech)Minarelli. Is it even conceivable to swap the Minarelli for a GY6 150cc ? It would be quiet, cheap and still one of the nicest handling scooters.

I'm thinking the frame brace will go in like this. Not yet welded.  |
