GL1100 carb intake runner bolts and washers

Postby Aussie81Interstate » Fri Mar 20, 2015 11:07 pm



Hi,

Just removed my carbs for a refresh and was wondering if this is correct.

When I removed all 4 intake runners I noticed that only the outside bolt on each side had a flat washer underneath it - the inside bolts did not.

Is this correct or should ALL the bolts have flat washers???

PS - I didn't have much trouble in removing the carbs - just removed the carb cover on #3 and all intake runners - slid straight out. Although I did experiment with the petrol tank moving it backwards - didn't really need to do that.

I might polish the tops when I get them back from the mechanic, and do the intake runners as well. It will look good for a while.. :D

Mechanic is going to take some before and after pictures as well - let me know what he finds inside them - I know there is already some junk in them - as coming back from a 600 km round trip last week - the last 300 was running on 3 cylinders- used lots of fuel.

Basically the bike would rev freely - but under load it would not run cleanly at all. Backfiring a lot on deceleration and popping under throttle load. Could not pull up a slight incline without dropping back to 4th gear and had to keep revs above 3500 to keep going. Used 15 litres (approx. 4 gallons) of fuel in 141kms (87 miles) or 22 mpg...not good.

Ran a compression test this morning motor dead cold
did not adjust valves at all - was done a month ago - could be a little out of adjustment

Cylinder 1 Dry - 130psi
Cylinder 1 Wet- 140psi
Cylinder 3 Dry - 130psi
Cylinder 3 Wet- 140psi
Cylinder 2 Dry - 132psi
Cylinder 2 Wet- 155psi
Cylinder 4 Dry - 120psi
Cylinder 4 Wet- 135psi

let me know what you think


thanks

Charlie

Washer on all the bolts is stock..your compression is way off shouldn't be more than 5 lbs. difference. reset your valves and try again. Below 140 is min for rebuild..but the bike will run at 90's. If after you reset the valves and the numbers don't change much try added a little oil to each cylinder before you crankit..if the numbers come up it's the rings if not the valves.

Read the information a bit more clearly - I have already done a wet test. plus I indicated the valves hadn't been adjusted.

Thanks for the replies and your comments
