Thanks CW.
How much did you have to lower the engine cradle by to fit the XL engine in?

Also the 175 engine was supposed to be hard to get any decent  power out of. How'd it go w the Poweroll 225 kit?

I bought the bike this way,  they cut the frame just in front of the pegs anjust below the front motor mount and made the engine a stress member, then they made a really fancy skid plate out of stainless steel and welded to the frame below the engine.    Looks like they needed about 1" clearance.    As far as the 225 powroll kit,   Its still a turd, but it has a ton of torque.

Your bike reminds me of my friend Eddie Phipps 4T Elsinore. His has a Powroll stroker XL350/480 engine which is waaay too much engine for the chassis. It'd be a much nicer unit with a 250/305. Despite the power overload, it's a nice conversion, looks factory.

All done,    shortened the rear shocks by 1" gives the bike a better stance and I can touch the ground, finally finished the air box,  this thing should rip,   been to cold to get outside, will post some action shots when it warms up!!!!!!!

I think Geoff is bang on with 385mm shock length, my bike sits level with the Foxy Forks in their mid position. My final assembly was going well until the paint fell off the frame....  >:(

I've been watching that bike.. Very cool. It must have the lowest seat height of any HL i've seen, bit more practical. Could probably touch the ground on that one. :D

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=320329299466&viewitem=

The bike that is on ebay is the same one that was on Marks vintage swapmeet last summer, it has also been on ebay a couple of different times, it had a primer grey tank on it,    The tank that is on the bike now was also listed on Marks vintage swapmeet,      THe guy beet me to it,  oh well,    it makes for a ncie finish to his HL     I been watching its progress and a few stickers, a tank and some controls and the guy has almost doubled the bid on the bike.   


 I took my HL out yesterday, and this thing is a monster, I have never rode a TT engine with this much power,  I put an IRC 140 x 18 rear tire on it and man you talk about bite,  zero wheel spin.  we rode about 40 miles of verytight and technical trails, thru some tall pines in the national forrest in Missisippi.  There were a few guys that just couldnt believe how well the HL handled and run,    its amazing that a 30 year old bike can perform with modern machines, or pretty darn close anyways!!!!
