Moderator Cynic Posted July 20, 2014 Moderator Share Posted July 20, 2014 The cap resistance and plug resistance have NO effect on the cdi its electrically separate. What resistance do dyna reccomend. Personally reducing the resistance of the ht coil output will make a huge difference to spark energy (its only rf suppresion anyway). Ohms law says so.

Moderator drewpy Posted July 20, 2014 Author Moderator Share Posted July 20, 2014 well this is strange, wired in the new pickup coil and it didn't spark again. shortened the lead and it sparked! got continuity in the loom, so maybe its the ohm thing. got the engine going, but wouldn't rev at all, pulled the carbs but they were clean (from the last job) I do have another pickup but its 290 ohm with 1.5acv as opposed to 98ohm with .8 acv any thoughts on using that one?

dt502001 Posted July 20, 2014 Share Posted July 20, 2014 It's always the small shit that you over look glad you finnaly got it at least running. Could you even get it to slowy rev up if you only gave it a wee bit of throttle? I think I would be more tempted to try first,removing air filter and try it,then blocking air inlet. just to be sure it's not fuel related as you have the smaller carbs on it,and getting some non resistor plugs.

I'll check it Tommy, but there's only the loom in the upper frame that's original.No chance of any oil soaked wires there. Link to comment Share on other sites More sharing options...
dt502001 Posted July 21, 2014 Share Posted July 21, 2014 Well unless a guy like newmamirconsa'snitsler who might live in his own camp just soaked it in oil every wheh has no effect on the casing of the wires and the copper core within then nNo ER um YEs no yes...,,and well you know it rains so,,,er ,,um forget it. You got it this far now stop and think,,, small things!! You might have over looked.................................................! 95 % of the 400 time's you have looked at something you thought "well it is good /or should work " Is when it bights you in the ass, Knowing your bike and knowing you did it, is, all that gets you home sometimes Link to comment Share on other sites More sharing options...
feliks Posted July 21, 2014 Share Posted July 21, 2014 If you need any specific pictures of anything let me know and I can snap em of my FZ - the engine is currently blown up but I plan on fixing it, however maybe some pictures or info will help you at this point... just let me know!

Moderator drewpy Posted July 21, 2014 Author Moderator Share Posted July 21, 2014 thanks felix, i have an fz engine in the shed. just ordered some non resister plugs as maybe the dynas have resister silicone leads. ordered some oil for opie too Link to comment Share on other sites More sharing options...
dt502001 Posted July 21, 2014 Share Posted July 21, 2014 That would drive me nuts having to order and waite to do anything,any day but sunday I can have parts I need in hours or minutes unless it has to come direct from yamaha then its 3 days. A small thing like spark plugs 15 minutes and I would have new ones in my hand. I don't get it with the number of bikes on the road your side I would think there would be bike shops all over the place. What's the average waite?

dt502001 Posted July 21, 2014 Share Posted July 21, 2014 and time to make brews Haha or drink them I guess would still drive me nuts when in the middle of a project and needed a spark plug .Every bike I have ever owned since resitor plugs came to be I replaced them with Non resitor plugs,I dont care if richy rich in his bemmer radio goes buzz when I drive by 1 Link to comment Share on other sites More sharing options...

I don't get it with the number of bikes on the road your side I would think there would be bike shops all over the place. What's the average waite? We have way more rules over here. Insurance etc. Plus bikes are far harder to keep running. Things like the split o ring on my TDR. Yamaha wanted me buying a complete tank assy. The o ring isnt a single item anymore. Then chuck in the mot. Which we need every year. Not to mention insurance. People buy new instead and get rid at 2 or 3 yrs old. Only dealers messing with them because of the electronics. Net result a split in motorcyclist types. There is us lot. Do our own work and route out parts to stay on the road riding our bike trusting our own skill and being the dieing breed that will admit their at fault. Then you have the people that wouldnt know a spark plug if you hit them with it. They want the fancy helmet. The leathers, whatever boots Milandi is wearing. Pah. Net result bike shops full of useless crap for the most part. All my stuff comes from Fowlers in Bristol. You any nearer Andy. Link to comment Share on other sites More sharing options...

Moderator drewpy Posted July 26, 2014 Author Moderator Share Posted July 26, 2014 plugs in, chuffed a bit one one cyl. bastard lit me up when testing (thats the dynas) reckoned it was the in-line fuel tap I put on causing an erratic delivery, then POW it lit up just putting it back together now and check that it charges and going to order a DT400 fuel tap and eliminate the vacuum system. the crmc boys who race FZ600's in the UK all put them on Link to comment Share on other sites More sharing options...

So relay box gone and kill switch working and this night mare was mainly because of to much resistance in the plugs? Link to comment Share on other sites More sharing options...
