WaveDemon's 66e SJ Conversion - new ride report.

[blaster800]

disconnect the pv motor from the harness , looking at the pv electrical coupler with the plastic lock at the 12 oclock position , hook batt pos to the right terminal, hook batt neg to the left term , touch a jumper from the left term to the bottom term for one to two secconds , upon removing the jumper .....the pv motor will cycle 105 degrees which is a lil more than 90 degrees when looking at it ! if it cycles its supposed to be good ! thats all it does the rest of the controlls are ignition controlled

You don't need no stinking power valves. :mischievous:

You need non P.V. 60T cylinders and pistons. :biggrin:

see what happens when you try to get all fru fru. :smile:

the electric PV motor is toast. Tom came up with a good fix that we'll try out.

 

[WaveDemon]

I decided to eliminate the accelerator pump and rejet. I used some jetting suggestions from Greenhulk for a single piped 1200. Unfortunatly from idle to 1/4 throttle is way off. It falls on its face but once it gets to the main jet circuit it turns into a freaking rocket! Way more power up there than I expected. I hope to test it again by this weekend with some jetting/pop off changes.

Most of the guys running the 66e and 65U's on the GH are throwing those 1.2 needle & seats in the trash and are replacing them with 1.5 or 2.0 and the 60T are using the 2.3 needle and seats.

This seems to be the most popular jetting for a 66e with raised compression.

115 Pilots
135 Mains
1.5 N&S
95 or 115 Gram Spring
1-1/4 Turn Low Speed Screws
3/4 to 1-Turn High Speed Screws
No choke plates or accelerator pumps

I run 44psi pop off on my carbs with Factory pipe twins with a 1.5 N/S

Edit for 66E with factory twins here are the jetting specs from Factory pipe

Disable the stock accelerator pump. An optional diaphragm cover can be purchased to
completely remove stock accelerator pump.
Main Jet : 185 front (Mag) carb, 185 rear (PTO) carb.
Pilot Jet : 95front (Mag) carb, 95 rear (PTO) carb.
High Speed Screw: 1-1/2turns out front (Mag) carb, 2 turns out rear (PTO) carb
Low speed screw : 1-1/4 turns out both carbs
Needle & Seat : (stock)
Spring : 95 gram (dull silver)

You could probably just remove your 185 main jets running that 1.2 needle & seat and still have the same effect. :scratchchin:

Probably! I am drawing a blank on what jets I have in my carbs (its been a few years shoot I need to do a rebuild on those things now that I am think about it) anyways my jetting with a pet2100 ending up being alot different then what Factory Pipe said to run.

I'm sure leaving those 1.2 n/s in was giving me a lean condition. Thanks for the advise and help chris. I'm really starting to feel like I made the right choice with this build.

Hopefully my new servo motor will be here in time for the next test run.

Im running:
Pump removed
120 mains.
130 pilot
1.5 ns
silver spring.testing tonight again..
My first run was
2.0n/s
stock spring
95 pilot
stock mains = way to lean on bottom , and like mentioned above took off after lowend was passed.

 

[astral]

Also I synced the pop off by cutting 1/4 off of rear carb spring.There within +/- 1 psi.(helped)

 

[WaveDemon]

for a few different reasons I haven't had a good ride or fixed any of the ski's problems... until now. It feels great, great power everywhere. I've got it jetted like a PV1200 with a single pipe. I'm sure I'll get more power out of it with a little more dialing in but I'm real happy with this base setting!

 

[CARBONX2]

The chamber you are using is too short for the port duration of the 66E, building another one longer will give you an increase throughout.
The b-pipe header/1st diffuser strangles the motor a bit, but easier than building another one.
Would be better to shut all the water injection screws and waterjacket the new chamber to make it a drypipe. A decent set of carbs, drypipe and programmable ignition will give close on 160hp

nobody said it got to be pretty!!!!!!!!!!!! as long as it works.

True that, I 'm no model and get ridden oftenly

Anyways, great work, maybe one day I will be able to swiftly and relatively cheaply install a 66E in my babe...
