Anyone got any suggestions on this?
We're talking about the point where the exhaust system bolts to the exhaust port of the engine.

The manuals for scoots with 6mm studs tend to say around 6 to 8ft-lbs (72 to 96in-lbs).
I must admit I just get those tight by feel. Then I check them again after the first ride.

I tend to just tighten them by feel as well. But one of my scooters (Taotao VIP 150) seems to lose those caps. I just laid in a supply of 20 caps and studs. 'Cause I figure I"m gonna need 'em.
The last time I tightened them up I coated those threads with muffler sealer. And one of them still worked loose.
So I figure this time I'll coat the threads with blue Loc-Tite and torque them just right. |

On the exhaust studs I've been using little lock washers to keep the nuts in place. I don't get many loose ones. I tighten by feel not torque wrench(don't own one haha).

The 150 that I have lost one of the acorn nuts that came with it stock on one of it's first rides with it's past owner. I installed 2 regular nuts on each stud after that and it was fine since. I do the same if I use studs on my 2Ts and there's room.

wow, I never knew the torque value was so low. I have been way over torqueing them. never lost one, and only once did the stud come off with the nut, which didn't bother me any. I like the ones that have the alen head, so you can use a regular socket or an alan key

I just rebuilt my 2014 with a 52mm BBK...I have all the required torques if you need them.
I had to change my head because on my 50mm BBK I stripped the spark plug hole out after about three yrs of not using a torque wrench, so I upgraded to the 52mm HocaBBK with the Taida racing head
huge gain in power

Better for them to fall off than seize to the stud.
I just do them by feel, but don't lean on them too much, or you squash the gaskets.

When you have loads of experience you can "feel" what nearing 100 inch pounds is. If not...measure it. The biggest time waster for us, is having to work out a broken stud...we do 5 or 6 per week, so we are good at it. It sucks! Here are some thoughts: If you have a thick exhaust pipe head flange...leave it what seems hand tight. If it leaks at first start, leave the engine running and just tighten equally, until it stops leaking. Drive it normal...let it cool. If you do have a way to measure...set the wrench value at 90 inch pounds and check. Tighten to 95...that's it! 5 more pounds than leak value + a few...room to tighten more if needed, not to exceed 100. If you have one of those thin flanges with the opposed dog ears...get a good pipe. If not possible, you will have issues. They will bend with very low torque values...once bent, they're no longer reliable. We have cut them off and installed a good one. No pipe waste. Here is a good rule to follow: Never use a 3/8" or larger drive for an inch pound spec. Human tendency is to over tighten everything. 1/4" drive lends itself to a better result here. |
