  1. If you don't like getting your hands dirty are you you've made the correct choice with a XR...................? You need to service a oil bath air filter on a old crawler tractor that's full of mud.............that XR filter wouldn't look bad at all! These are off road motorcycles that operate in all types of conditions.......the filter has to be shielded properly. Lots of design goes into these air boxes.............and for good reason! As far as carb access ...........ought to try pulling the carbs on some of the 4cyl street bikes! Old School Al
  2. Have you ever tried a Filter Skin over the Twin Air? In this area we encounter thick talcum powder dust during the dry season and a Filter Skin over a Twin Air is the best filter set up we have run. Old School Al
  3. None of the key people at Powroll would have made statements like that on intake valves for small Honda singles.................total BS! With all the tech you offer you should know better anyway and have called BS if they had! I thought we had you up to speed on this after the last time you brought this up on the forum.............? Old School Al
  4. OEM................................! Old School Al
  5. I have no idea what makes Chuck think the intake has a hard coating...........multitasking again? Intake valves are soft with no hard coating..............that's why they wear so much! While excessive lapping is not good, you'll wear out before the coating does on the exhaust valve hand lapping. On valve guide clearance the tried and true method is to lift the valve just off the seat and wiggle the valve in the guide.............the way the guys that have to stand behind their work have done it for years! Old School Al
  6. You want to see if the ring end gap is within spec............in this case (excessive smoking) too much end gap. Also check gap at different places (worn and unworn) in the bore and compare results. Has the cyl been bored oversize...........? If the cam lobes are worn, the rockers will be also. What do the cam bearings look like? Old School Al
  7. Were you able to figure out what you have......................? Old School Al
  8. How much ring end gap do you have............? Is the cyl standard bore or oversize (bored)....? Old School Al
  9. Thought I'd pull this up to the top again to see if we can get more comments on this discussion...........? Any more theories on exactly what the damage to the engine will be if the head is not removed to install a Helicoil in the spark plug hole, and some of the aluminum chips are left in the cylinder.......? Old School Al
  10. "Destroy your top end"...................exactly what do you feel the damage will be? You are aware the few "metal shavings" are soft cast aluminum, and are rings and cylinder are much harder? Have you ever fixed a 2-stoke engine with a badly holed piston, and the entire engine blown full of aluminum requiring a full tear down (case split) to clean up? How much damage was done to the rings or cylinder ("top end")............? A few little aluminum "metal shavings" will be quickly be blown out the exhaust with no damage at all............ Old School Al
  11. The choke has to be open so we can see the bottom of the slide ............the choke plate is blocking our view. The angle of the first pic would be perfect if the choke was open/off. Could you take a pic................then completely remove the idle speed screw and take another? Note free play in throttle grip with idle speed screw removed also. Old School Al
  12. I think you've been nipping on the BS Booster on us again Octane Arthur...........!!! Old School Al
  13. Ok...........thanks for the info! Great place for the Chinese carb..................we need to send them a message and quit buying second rate junk! The is no spec other than rpm's for idle and 1 3/4 will not work. Once again back that idle screw out a couple turns. Can you pull the air intake tube so you can see the carb slide and take a pic of the slide in the closed position and post it for us? Old School Al
  14. Yep.........looks like a (rear) brake light switch. They are just a make or brake switch with a over travel spring to protect the switch from damage. Pick one you like and go for it. Old School Al
  15. If it can blow the head off...........blowing a turd out of the pilot jet shouldn't be a problem I would think? Old School Al
