How much metal can "safely" be removed from the front mount?

I'm thinking it's grinder time..

other pics of my dumb@$$ choice of a bike:
NEXT Avalon... Jet "80"cc stealth.... will it fit?

on my old bike i cut a notch in my frame instead and it worked.
but you should not grind or cut anything,you should get longer studs,they should have come with your kit,is the back studs longer,if yes swap them for the front ones.
if not go to the store,bring one of your studs with you and ask for a metric long stud rod the same size as yours but longer.

Can use bolts and cut the heads off. (easier to find) I forget the size and thread, but some one will know off the top of their head or just size at the hardware store. Part of the fun is making it all work and after all the hair pulling, you will be even that much prouder of your build!

Noob,
You can safely grind enough to make the saddle portion of the front mount fit your downtube. It won't take much and and the aluminum is easy to remove. If you have access to one, a Dremel Tool with a sanding drum works well. Work slow and check your fit often while grinding. You will be fine. As for longer fasteners there is no requirement for them to be studs with nuts. Allen head cap screws work beautifully and you'll find the size you need in a grade 8 bolt at Ace Hardware. I've attached a photo of my rear mount using the Allen head cap screws instead of studs. Sorry, I didn't measure them so I can't give you the proper lenghth but finding it isn't hard. Double nut a stud, screw it in until it bottoms out then measure the amount of thread in the block. Add enough to reach your clamp with a lock washer subtract about 1/4" and there's your length. Good luck, keep us informed.

..and your just telling me this now Tom! LOL, Have 2 hex head bolts on the Honda, with the heads still on.

Kidding aside, thats a great and simple answer to the treaded rod/stud quest. Thanks.

just thought of this, would make removal a snap too! dang. Where were you about 9 weeks ago?

thats a great idea using bolts and leave the head on,easy to tighten and loosen and comes in diffrent lengths,i wish i knew that before my 2 builds.

Still might find them in the size lenght you need if? Then put a nut on the stud you need to make shorter . Then use a hacksaw after unthread the nut. Viola you'll have clean threads again. If it is a grade eight then the sharp corner of a file can help you will prob need a die. Anyway carefully cut if you have to with a hacksaw is do able.

I added a picture to my original post but it didn't show as an update. Just scroll back to link #4 for a pic of Allen head cap screws in place of studs. I also added some info on sizing the bolts.
