    Well, I didn't think it would happen to me but today it did. I went for a long ride today and when I got home I checked out my motorized bicycle. As it turned out, I was missing a nut from my muffler and a nut from where the engine bolts on to the frame. At least it was nothing too important... lol..

    It looks like I might have to go with Loctite or something like that. I don't want to have to keep checking these nuts and bolts every time I ride. That's no fun.. lol.

    Thanks for lending an ear.. Just had to say what happened.

    Double nut them. That works best. Do not use loctight. Enjoy the ride...

    Loctite everything and check all nuts and bolts on engine and bike before and after each ride....

    Sometimes double nutting is not possible...if you use loctite, make sure you use the proper type for your application.

    From what I've heard, Blue Loctite is the way to go. Not Red. So that is what I'm planning on getting. I know Duane says don't use it but he's the only person who has said that. Duane can you tell me why you think I should not use the blue loctite? Thanks man.

    Loctite tips-

    Use medium srength for more applications. High strength for those stubborn fasteners, and sleeve retainer for stuff you don't want to remove.

    Do NOT get any on your fingers and then smoke, or any on any smokeable item....it is very poisonous this way. (it doesn't taste too good plain either).

    Read the directions on the package before you throw it away, you can't read the writing on the tube!

    Shake well before each use.

    Don't over do it.

    Re: Things falling off mb

    I found my luggage rack hanging by one support the bolt was gone from the other.

    Most embarrassing was the support I bought this morning to use for my new bike. I was riding home with it stuck in my carryall on the luggage rack. Well that didn't hold it. I heard it bounce on the road but I was in traffic so I lost it. But I can image the cars around me trying to dodge it.

    I need the loctite the will never let go cause my drive wheel on the chainsaw bike keeps getting loose.

    So far I lost two set screws to one of my sprockets but I think the nut behind the wheel was loose.....:p

    I figure I don't worry too much about stuff falling off unless I slow down.

    I've never had any engine mount stuff come loose, but I used new well made nylock nuts....they seem to hold well. Also, as my engine broke in it got smoother and smoother, so less vibration to loosen my precious nuts.

    Thanks for all the help about the loctite and stuff. I just noticed that all the nuts and bolts had vibrated off of my back fender too. Need to get that fixed too. Thanks to everyone for your help. I need to stop this from happening or I will lose every thing

    Nylock nuts are available at True Value. Just stock 10 or so of 6mm. The only 8mm are the head I think - can't use Nylock nutz there. The are some small screws - 4 mm and 5mm as well, no??

    Yes..If you use loctight, and you bought your engine from me, you will void your warranty. You will ruin the motor. First of all, loc tight is not necessary , . I have done over 300 installs with thousands and thousands of miles, and never had to use loctight. First of all, as your motor and bike breaks in, you will need to tighten your nuts and bolts down more. Loc tight will not aid you or help in this. Also, if you use the wrong loctight, you will prevent the tightening or removal of nuts and bolts. If you have a concern with a nut getting lose, go to a nyloc or double nut them. If you use glues, you will ruin those connections or at least make those connections hard to deal with or maintain. thanks.. Enjoy the ride..

    Re: Things falling off mb

    so far nothing has fell off my bikes except me will loctite help with that?
    Naw! I do use it on the bikes along with lock washer all of my hardware is what came with the bike engine kits I 've installed the parts and have yet to re tighten them except the head bolts on the Dax engine and I believe they came loose due to heat cycles but still haven't had anything fall off and no sheared mounting bolts. One chain guard broke by the engine due to vibs. and I re welded it.
    Could it be I'm taking them apart too much to do how to posts?
    Maybe the god of tight nuts is smiling on me!rotfl
