Rod,
I feel your pain. Outfitted with gear I may be just a little over that, so my choice of motivation is a 250, but I hope with a little working out over the winter, I can gravitate to a 175 77 MC5 and move out of post vintage open class once I get the bike built. Mike

Maybe the question should have been Bigger bodies = Less power?

Dwight,

I wish you had sent me an e-mail when I asked a few days ago because I cannot seem to master exportin a photo on the POG board. I wanted to show you phots of my bike being the ONLY 125 to do double jumps (that were not even meant to be double jumps per AHRMA).

After that day I had to throw away my square rims and straighten out the forks unless I wanted the extra 3 inches of wheelbase[:p].

The modern rims are on my bike to keep me out of the hospital. I dont ride my Penton like most people and most of the mods are done to help keep me intersted by feeling that I am continually improving something on my bike (FOR ME). If I can't stay interested there is no reason to race. As cowboys say "The pay just aint that good".

If anyone ever protests my bike I may ask them for gas money home and they can keep the bike. "The pay just ain't that good"
TB:) Have a good weekend while we got em'.
GO PENTON!

  As long as you are expressing your feelings so am I.  Your ideas and thoughts don't always match others as well as what I think doesn't always match what others think.  I hope all of the Hodakas you are racing now are stock.

Ron, care to do a tear down ?  I have raced completely stock Hodaka 100B  bikes even down to the stock shocks.  My MX Combat Wombat is STOCK except for the Progressive suspension shocks.  My ISDT Combat Wombat is STOCK except for the added light kit and Works Performance Shocks and plastic front fender.  OH, I added a Wombat luggage rack and Wombat tank.  The engine is completely and painfully stock. Just carefully jetted.  It has a whopping top speed of 55 mph.  
I am going to stick the engine back into my Jackpiner right now.  Back later.

Dwight,
  Thanks for the email, but I didn't attack you.  I was just stating my thoughts just like you did when you wanted to make a point.  I made my point and if ALL your engines are totally stock then you made your point.  I like enhancing engines with what I feel makes them do what I want them to do in this day and time.  Just my thoughts and since you made your thoughts public I felt like I was at least possible able to make mine public...maybe not?  From now on I just won't post anything in the same post that you give opinion on since it might interfer with your higher thought pattern.  That's it.

I am sorry if my comments have offended anyone and I pointed out that my comments were only of my personal opinion.  I also said that anyone is free to do what they feel is right.  But personal attacks have no place on this forum.  Ron your comments are most welcome.

Dwight,
I am sure you are a great person and have plenty of friends and followers. I know from experience that things can get twisted through on line chats because we miss out on the valuable face expressions and vocal tones of a normal conversation.

Suggesting I do not listen to Doug, Dane and the lot of excellent Penton people could be somewhat viewed as a personal attack as well as the fellow that misspelled vinyl.

Lets move on and let this thread get buried into the unseen archives where is belongs. I am going down to take my 6 Days down to the frame, full glass blast, paint and start over again for 2007.
PEACE

Could you or Ron send me the Jetting specs for your 32mm Mikuni carb. I have some 28mm Mikuni carbs I want to put on my Six Day and my Zündapp GS125.  Probably similar jetting. Both came with 27 Bings.
Pax,

I will be tearing my 32mm Mik apart Sunday AM and will send it. Big UPS (as my son would say) to Donny Smith for the specs. Two seasons of race punishment without a failure.

In 2005 my friend saw me unload the bike after 1100 miles to Texas and it actually started 1st kick. Not the case with his Yammy.
Thanks again Donny.
PS- Funny part is Donny misplaced them in the move to Arkansas and e-mailed me for them last week.:) Donny..they are coming.

32 Mikuni:

3.0 slide
Needle Jet 159 8N
Jet Needle 6F4 center clip
45 Pilot
160 main...I plan to try 170 main for break in of new bore, then go back.

I remember having to read jets for my dad. Now I have to use a magnifying glass and get in the right light[xx(]

I think IRC makes a good tire that measures out about 4.00 they call it 102mm overall width, that's about 4.020in. The model is the M33 110/100x18 sounds fishy but that's what their web site says? Gavin p.s. My dear departed friend Kendall use to say "Bring what ya got, ride what ya brung" let's just have fun :D
