Replied by GFrench on topic Re:GFrench - EnduroRide Special
Thought I would give a quick update on the Black Widow- likey
This image is hidden for guests.
Spent some time yesterday riding and continuing to dial the bike in and man o man she is now off to the races! Throttle
I decided to pull the 15/45 sprockets and go back to a 14/39 set up and now have the perfect combo with strong low end pull- Wheelies! while getting more mid and top speed range.
Here is my current set up with the RT1MX 34mm carb-
Main Jet- 260
Pilot Jet- 60
Needle Jet- P-0
Needle- 6DH2- #2 slot
Air Screw- 1 1/2 turns
Valve/Slide- 2.5mm
I received my new slides from Sudco (2.0 & 2.5mm Cut-away) on Friday and man they are the nice "heavy" brass style vs the Aluminum that Yamaha used back in the day.

I was told by more then one person at Sudco that these aftermarket slides would not fit the old Yamaha carbs- Well they are WRONG!
They have the exact same specs and fit perfectly. I am a new believer in the 2.5mm cutaway as it allowed me to dial this bike in perfect.
I even put the 2.5mm in my 1976 DT400 and made a HUGE difference vs. the 3.0 stock slide. No more surging/ jerking as the bike idles down.
Looking at my plug- still a tad rich which is good so will be taking one step at a time to get it 100%- Next step is to take the pilot down to a 57.5 as this should be my final adjustment.
I knew this bike would deliver some amazing power and pull really strong thru all 5 gears- a lot of hours invested trying a lot of different things and the reward is just amazing when you finally hit the sweet spot!
The real key to solving my issues was going to this bigger carb!
Will get some video shot tomorrow of the bike running thru the gears- stay tuned.
