Fire-medic, you provided this advice on another thread and I did make an attempt to reflow the solder. I have a decent soldering station setup and faithfully reflowed the solder at the circuit board connections, but it did not resolve the issue. I then tried to remove the solder from the...

Follow-up to close out this hanging thread. I discovered that the misfire/backfire was caused by poor spark as a result of a faulty TCI box. Under low speed conditions, the TCI would not reliably spark the plugs, causing an erratic idle, poor take off, and misfire/backfire. Swapping out with...

Thanks for the advice guys. I'll find a head that includes the caps, but won't worry about finding matching cams. I'll check clearances while I'm checking the rest (conrods, mains, etc.)

I've had a significant setback in the restoration process for my '85 Vmax. I am in the process of rebuilding the engine (2nd gear fix) and I paid a friend with a powder coating business to strip the paint from the engine parts. Most came out well, but for unknown reasons (I have my...

I replaced my faulty stock 1988 TCI box with a "TCIP4 Full" Ignitech unit. The unit was pre-programmed at Ignitech to match the stock box performance. It looks like these things have some serious versatility. Question for the group...I'm planning to keep the bike in stock form...is there any...

You guys are great! :D I'll get out the micrometers and the bore gauge and see if that illuminates the situation any.

Thanks for the advice fellas! I've rebuilt many engines, just never made this particular mistake before. Looks like I'll need to pick up some plastiguage. I think I have two pistons identified based on barely legible tags and can put them back in their respective bores (sound better Mr...

I'm in the process of rebuilding the engine from my '85 (2nd gear repair). When I pulled the pistons/rods, I put them in individual bags with tags identifying which holes they came out of. Unfortunately, the residual rust protectant I had on them dissolved the ink I'd used on the tags. Stupid...

I've had great luck using these diamond bits to slowly and carefully eat away the broken parts stuck in the hole...whether its a bolt, driver, tap, or easy out. https://www.harborfreight.com/diamond-rotary-bit-set-4-pc-69664.html

Does anyone have a set of these they'd be willing to part with? If so I'd appreciate it if you could hit me up with price+shipping to 50643. Thanks, Chris

Does anyone know whether the OEM spark plug caps are resistor or not? If so, what resistance? I've purchased some aftermarket NGK caps (SB05F) w/ 5kOhm resistors and I'm trying to figure out whether they pair up properly with the OEM NGK DPR8EA-9 resistor plugs or whether I should get the...

Just took delivery of my new front tire from Chaparral and it was manufactured in March of this year. Lesson learned...if manufacture date is a concern, buy tires from higher volume dealers and not from one-offs on eBay.

Thanks for the feedback fellas. I sent the tire back and ordered a replacement from Chaparral Motorsports. Hopefully their throughput is high enough to keep newer stock on hand.

I just received a eBay purchased tire advertised as "Brand New". While it is certainly unused, the manufacture date is week 19 of 2018. I have several motorcycles I ride and tire life is determined by time and not wear as I don't put much more than a couple hundred miles on each per year. I'm...

Back and forth several times...problem follows the '88 TCI. Guess I'm in the market for TCI...they're cheap and easy to find...right? :(

UGH!!! Guys, I think its the TCI. I swapped in the TCI from my '85 and the problem went away. I'm going to switch back for good measure...tough to be sure you've got it mastered unless you can turn the problem off and then back on again.

Just spent a sweltering couple hours in my hot garage checking the entire ignition system and everything checks out per the specs in the manual. Ingnition coil resistances, pick up coil resistances, spark plug wire resistances are all to spec. I pulled all the connectors from their housings...

Working on checking those now. Thanks.

Firemedic, thanks for the response. To answer your questions: I pulled the plug wire spades from the connector housings and cleaned them on the coils. I "unmounted?" the spark plug wires from the coils and cut as small section from them to expose fresh copper and reinstalled them ensuring...

Strange situation that has me perplexed. My '88 Vmax will idle reasonably well, but it's only running on the front two cylinders. When you crack the throttle it stumbles a little, but then the rear two cylinders start firing and it rapidly climbs RPM. I've pulled each spark plug cap...
