[UPDATE: Bike/Me Hit by Car] 1980 GS1000G --Fresh Build-- Hesitation at High Speed...
[Check Page 4 for Update]
Oye!
So, I finally got the bike registered after a bit of some hoop jumping... But, hey, she's street legal!
After patching up the front end this morning, I decided to take her for an extensive test ride.
Here's her aftermarket mods for troubleshooting's sake:
- 4 to 1 exhaust
- $20 Pod Filters off of eBay
- DynoJet Stage 3 Jet Kit (170 Main Jet)
She feels fantastic at low speeds and accelerates evenly in every gear. I cruised around town for a while and made my way out to the freeway. When I got on, I accelerated up to speed and at about 55mph the bike started to hesitate... I kept my throttle position in order to feel out what she was telling me and she would lose power momentarily and then even out, lose power, even out--all very intermittently.
I had to run to work, so I didn't get a chance to trouble shoot, but I'm thinking one of 2 things is the issue:
Either
(1) The 170 main jet is too big with those shit pod filters and she's getting too much fuel.
or
(2) There's an air intake issue at high speeds and she's got too much air coming in.
My thought is to pull the plugs and check if she's running rich or lean. If the plugs are fowled, I can clean them up and try the Stage 2 main jet from the DynoJet kit (I think it's a 118). Alternatively, I could take the pod filters off and run it open to see if they're the weak point. If it runs right without the filters, I know I need to get me some high flow K&Ms, STAT!
Thanks for reading. Any insight would be awesome... This is my first build, so I'm still making pretty stupid mistakes... Like, all the time... But, I'm learning!
Cheers
