This all started many years ago when I thought it would be really cool to have a 2 stroke engine in a more modern chassis and street legal.
A few ideas turned into the purchase of some parts and it began last year. ( i kinda went ADD on projects and the Bronco received no work and as a few of you noticed I fell off the face of the earth here
)
I am stealing all this from another bike forum so as to not have to type it all again, please forgive me.
time frame was the weekend before thanksgiving when I made the trip south.
Enjoy......
It has begun, and is in full swing now.
Made the quick trip from Denver down to Albuquerque NM on saturday to trade my "too clean to tear apart" Hawk for another guy on the Hawk GT forums almost "too far to bring back" Hawk and a full race prepped RZ350.
Sunday after getting some much needed sleep after the 14 hour road trip on sat, I woke up, popped a monster energy and started unloading and making room in the garage.
decided since I cant afford(according to my mrs) a nice hydraulic stand I built me a wood one.
Redneck engineering at its finest.
Best part is since I am a pack rack it cost me nothing but some time. most material was wood leftover from my deck remodel last year.
not purty but will be nice to keep from being bent over for the whole time this project is happening.
Here is the new stand
with the Hawk up on it moves around quite easy and is 23" tall, I think it will work very nicely
here is the donor RZ
The Honda CBR600RR front end that will be sent out this morning and should arrive by xmas
I decided I had to fire up the RZ and take it for a quick spin just to get an idea what I was in for since Ive never ridden one.
Battery rigged from my SV, temp fuel tank.
added some water to the rad and fired it up.
main jets were a little big as it is jetted for 1600 feet and I am at 6000, so as soon as it started to come up on the pipe it started to fall flat but let me tell you this thing is going to produce some smiles when all done in the hawk and tuned properly for this elevation.
man I can't wait.
I told my wife i will see her in March sometime, and if she needs me to look in the garage
rear wheel HP should be about 65-70hp from the build sheet this engine has and I am hoping to have the weight down to about 275ishlbs.
Bike will retain its naked/fighter style with a large round headlight out front, it will have a single seat race tail either from A Honda RS125 GP bike or possibly a Honda RC211v moto gp tail with the exhaust routed either up under the tail similar to a Ducati 916 or very high with one on each side depending on what works out.
I think the frame and swing arm may get black powdercoat with the tank and tail sporting some honda HRC red/white/blue coloring with white powdercoat wheels.
at least thats the vision in my head, it may change 3 or 4 times before its done but that is where I think I want it to be.

the tear down.
have the next 6 days off so we'll see how progress goes.
some updates
Hawk engine pulled and rz engine stuffed in there to see how it fits.
Also dug my rashed RC51 tail from the rafters just to see how it looks.
Got some more work done last night.
had a bit of a slow start as a new toy/tool showed up and required some slight assembly.
I have a bench grinder, handheld grinder, files, and sand cloth but not a power sander, until now.
not the best there is but with the gift card my MIL gave me it came pretty cheap and so far works great.
this pic shows the series of engine mounts.
the front mount using the hawk bolt and spacers just slightly shaved down.
kinda crazy how well it worked.
this one is the rear mount, using the salvaged ZX11 "triangles"
here is the start of my bracket to grab the two 10mm holes under the engine.
bracket drilled
frame drilled and getting tapped
my small tap holder were too small so i regretably had to use a wrench, still works just way slower as its harder to keep straight.
1" square tube to mount under engine.
it spaces perfect to catch the rear frame mount with some flat strap.
the ends of the square tube will be capped and dont worry all the craptastic welds,
They will be cleaned up with a grinder and smoothed out to look clean even though they will never really be visible, it just needs to be done right.
tacked
welded
added some tube spacers to fill the gaps where the hawk engine holes used to be. allows it to be tightened without tweaking.
Please advise on the swingarm mount spacer, is it just a spacer or does that area have a function. IE- should it be a much larger peice of tube and maybe not aluminum?
I figured it just needed to be a spacer to keep the steel sleeves in the swingarm pivots but dont know?
Also I have been considering adding a bracket to catch the third hole in the zx11 mounts and having it welded to the frame. Not sure if it is needed for strength, but it can't hurt and will at least look to then be finished and will actually look like the braket was made for it instead of stolen from another bike.
Biggest issue is getting it welded as I dont own a TIG setup. Might see what the local weld shop would charge me to lay a few beads. It would need to be tacked as it is then remove everyting and take it to them just the frame to make their job easier.
here is the upper hole
and a quick rough example of the idea
weld the curved edge to the upper frame tube and then match the shape of thebracket on the bottom edge and drill it and slip a bolt though both of them
I think all in all it should be strong enough with what I have, and adding the welded mounts will make it a bit stronger and look more finished.
