I have done the most stupid thing! I was trying to get gone on a trip to TX! my haste caused me to crossthread the two left side screws!:XIs there an easy fix? I know I know you may ask how could I have done it twice! Haste is the culprit! Please without taking to the stealer and have them do some crazy cost fix, can I correct my stupid mistake here?

My wing is an 07!

You can try retapping with the original size thread and pitch or drill out slightly and retap a little bigger or install a insert like helicoil or time-sert

If you can get them out without damaging the aluminum threads, then clean them up with a tap of the original size. If they are damaged, then go for the helicoil.

Much better if retapping doesn't do the job to install a helicoil. A heilicoil repair is stronger than original and you can still use the original bolts. Over drilling and retapping means it will be much more difficult to repair if it gets damaged in the future. Any bolts that go into aluminum threads should have a very thin wipe of aluminum antiseize compound which will help prevent galling of the threads.

Here is what usually do if I cross thread something:

1. remove the nut

2. put some teflon pipe dope on the bolt threads this will act as a lubricant

3. Re-start the nut or get one with same threads making sure it grabs the first one or two threads straightly this time.

4. Then slowly tighten and loosen the nutin a manner where each time you tighten you go just a little bit more and each time loosen all the way to the first three or four threads on the bolt. Add more teflon dope if it gets dry and I am sure it will.



I have repaired several cross threads in this manner. Just take your time and I am sure it will work and save you tons of money in the process. By the way this works exactly the same if you are threading a bolt in only put the dope on the bolt threads.

I don't know about the 1800 but my 1500 has the seat threads in a tube that is threaded all the way through. I would tap it from the inside out if I could on yours.

If not I might get a type 8 bolt and run that through from the inside to anneal the buggered threads at the other end back out again.

I have done the same thing on my 1500, I assume. They are not all the way in at this time and I haven't taken them out to investigate. When I have time and the choice is ride it or fix it- I have been riding it! Was thinking about doing somethiing about it recently though as I have been looking for a used seat, somethng like a Corbin. Anyone know what size threads they are? I think both parts (male and female threads) on my 1500 are steel, not alum.

The parts fiche (at for example hdlparts.com) will show the size .. or grab a bolt and go to the bolt department of Lowes, Home Depot, tec. and find the size with the guides available hanging somewhere...

At first, I thought you meant seats in the carb. I assume your talking about the 4 cap screws that hold the motorcycles seat on. They are 8 mm screws. you can buy a 5/16 - 24 helicoil set which has the tap drill, the tap , helicoils and a tang breaker. the sae size is roughly the same o.d. as the 8mm and lots cheaper.Or you can get the mm kit. Either way you need new screws. I would , however, just try retapping with the 8mm tap first. Use one of the right side screws to match the pitch ( threads per inch ) on the tap. It's not a hard job .

They are 8mm x1.25 pitch. I just ran a tap thru the "nuts" and ran the cap screws thru a die and- what a difference! They work great now.

I too would probably buy new cap screws rather than a die- I just happened to have a metric set available to borrow. They would be expensive to purchase I would guess. The cap screws cleaned up easily but the nuts on the bike frame took some real effort and a good bathing with cutting oil.

You can find a good selection of metric hdwr at http://www.mcmaster.com and at http://www.fastenal.com. In fact you can buy both taps and dies on these sites too.

No.. a tap is for cutting new threads.. a chaser is for cleaning up threads that have already been cut... a tap can be used as a chaser.. a chaser cannot be used as a tap..
