    I am with you Ed adjusting shims on KZ's is time consuming and makes one a expert Helicoil repairer. I bought the entire Hot Cams Valve Shim 13mm kit on Fleabay for $56 shipped. I am currently low on 2.70 shims though. I received a Fed Ex box on Tuesday from NGK, response below. .

    Bench shimmed the GPz head this weekend with a Hot Cams 13mm valve shim kit. The valves are all set to the loose side. Pretty happy with the results now that all the valve shims are back in the middle of the range from 2.00 to 3.00mm. Took longer than I expected but what else is new. Accel spark...

    Anyone use Forking by Frank

    I purchased a set of BMW R100RS fork tubes from Forking by Frank in 1991. The quality was great and the price was significantly cheaper than OEM parts but that was before the business passed hands. He used to advertise in BMW Motorcycle Owners Association (MOA) which had a monthly magazine back...

    The cylinder head is now repaired with two new OEM valves lapped in #1. The machinist who repaired it was also to busy with large commercial machining jobs from local companies like Coorstek, Golden, CO. So I removed all eight valves and had SCH Racing Heads in Arvada grind all the valve stems...

    I shipped my NGK claim off today. I included several 8?10 color glossy photographs, just like Arlo's Guthrie's Alice's Resturant song along with the Kleeme Performance bill for the cylinder head work done in 2014. That's outa of my hands and I now I wait. Now I need a machinist who is...

    All bad news when I did a compression check on Friday, my setup #1 cylinder is where the spark plug insulator failed Rest were like this . . . 5300Ft NGK forced my hand had to have a look inside, it gets worse Looks like insulator residue, valves seemed to be straight but that...

    I found this on the NGK site but no guidance about what damage occurs The combustion temperature can rise to an abnormally high level so that heat transfer from the interior of the plug is unable to keep pace, leading to trouble such as cracking of the insulation and melting of the...

    After getting the Dyna S statically timed on Saturday 8/13, I hit the starter button and it fired right up. I only let it run for 30 seconds because the fresh engine paint, new rings etc. but the GPz was very responsive which is likely attributed to 1/4 turn throttle. I blipped it a couple of...

    I will start with the good because there is some BAD to follow. Regarding needle jet assemblies, I sent Chad Thompson @ Sudco a TM 27 needle valve assembly and he identified Sudco's P/N VM15/172 as an equivalent needle. No luck on the needle seat and each one cost about $25 and there is no...

    Thanks Ed for posting those pictures, that helps. Ray, I reinstalled the carbs, the float bowls are full and it hasn't leaked this week. I will try to start it tomorrow. If you have time Sunday maybe we can try again and shoot that video? Regarding the carbs, I contacted Sudco on Friday to...

    That would be nice, Ed if you get a minute could you post a picture(s) of how you use gray scotchbrite to clean inside the seat. The ID of those pictured are pretty small. So far no response from Sudco concerning replacement needle vale assemblies so it cannot hurt to try and clean what I have...

    No worries Ray, I am probably close to giving it another attempt to start it. When Ray & I attempted to start the GPz two weekends ago gas overflowed from both overflow lines which was likely caused by dirty or worn needle valve assemblies. The following Monday (7/25), I contacted several...

    I would agree. Its a good design that the warning light blinks when the brake light is not working. On the other hand not much value seeing the light comes on when you apply the brakes. Important thing its operating correctly.
