we had the kids birthday party today and my buddy came over. drove up in his new 2012 r8 spyder 6 speed v8 was nice. i didnt go for a ride or drive it today. next time for sure. i did however gladly offer to trade him keys he can have my car and non running bike told him it was a good deal. lol
I still have to check spark again and voltage at the coils. still not positive the last time i did the valves that i did it correctly. i may check again. the timing shouldnt be off as i didnt adjust it and it did run prior. at this point its either electrical or the valves. with what i know will be some minor adjustment on the carbs. the air/fuel mix may be off and they still will need to be sync'd.
definetly going to the garage tonight afterwork. going to check voltage at th coils and that i have spark at each plug. possibly check over the valves one more time not sure since we have to leave the house at 8 tonight to go to a birthday party. but hoping i can make some progress and rule out some items.
Carbs haven't been touched but were roughly sync'd to where it was set to prior to the valve adjustment. Carbs have gas. I do have spark at each plug. But they look a bit wet so I'm gunna change them. Valves were adjusted again a few were tight or loose. They are definetly in spec now. I took a larger feeler and was unable to fit but the proper size did. Cam and crank were properly aligned. Then I continued to rotate till I saw each came lobe release and then measured and only the proper size fit. Going to try and re assemble tomorrow with new plugs. I may pull carbs to try to bench sync and recheck that the pilot screw is 2.5 turns out and get a good base line on the air mix as I have no idea where it was set. Battery did measure a 13v today so that was an issue also also thats now fixed.
Not sure of what else I could be missing if it doesn't start after all this.
If you were getting a yellow spark id check the resistance across your coil. The manual should tell you what the tolerance is. If you are not sure of any settings on the carbs its probably a good idea to start fresh with all settings so there's no second guessing later.
Hopefully it fires and just needs a little tweek of the carb. If you still got weak spark then its time for some fun in electric trouble shooting. Hopefully your manual has procedures for checking the charging system.
No i was getting a blue spark and i had voltage at the coils. each coil fires 2 cycliners and they each measured half the battery voltage. The book didnt state what it should measure at but i think they are ok. Gunna reassemble tonight and pull the carbs off for another look over and hopefully this is my last check and everything works with some minor tweeking. if it doesnt work and wont fire im gunna have to check the compression to make sure i didnt bend valve with the wrong adjustments
Reassembled. Cranks but doesn't fire or even try. Compression test is my last option to see if I blew up the valves.Otr than that I'm sol.
