    1000 mile Pacific Northwest Circle Tour - Vancouver - Bellingham - WA Route 20 - Spokane - Creston, BC - BC Hwy 3 - Vancouver

    I have been planning to ride my lil Hondas on longer rides, and I am leaving tomorrow morning on the first leg of my circle tour - 400 miles from Vancouver to Spokane. I am riding my 1972 SL100, which I have replaced the tires with road tires, and added a rear rack. I have done 200 mile days on...

    CT90 Shifting Sticks

    I would not think that there would be any reving involved - I am thinking that the test is with the motor warm idling in neutral I hold the rear shift lever down, while testing the kick starter with my hand. The kick starter should move without any resistance, because the clutch is working, and...

    CT70HK1 Dies When Warm

    The perfect resolution to a Honda problem. No amount of their design improvements solved how to make these motors run without gas in the tank. I cannot tell you how long I worked on trying to get my 1978 CT90 K9 to start after installing a new carburettor to later discover that it did not have...

    CT90 Shifting Sticks

    Nate, this is really appreciated - I had never heard of this test, but it makes sense given my (limited) understanding of how the clutch works. Doing the test with the motor running makes me a little nervous thinking that if it is not working correctly I will experience a wild grinding of metal...

    CT90 Shifting Sticks

    I have still not opened my clutch, but it seems to operate acceptably, so long as I am no trying to shift multiple gears while at a stop. It only really comes up following an unexpected stop while riding in 4th gear. I just have to slowly get it back to first and not be in too much of a rush. I...

    Wheel Bearing, Speedometer Problem

    Wheel bearing issue resolved and speedometer back to reporting regularly. Smooth road tires improvement. Increased drive sprocket from 14T to 15T makes gearing work better for road riding. Replaced condenser makes running smoother and starts seem more reliable. Still need work at the top end of...

    Wheel Bearing, Speedometer Problem

    Update to the update...Thanks to Kirbby and OldCt, I have my SL100 running smoothly again. Well, actually, I know the wheel is turning smoothly and the odometer is running, so I am going for a test ride now and I am hoping that it is running better than ever! Further report in about 30 minutes...

    Wheel Bearing, Speedometer Problem

    UPDATE: I got the speedo gear out - not an easy job (upside down it sits too tightly around the spacer and it very hard to get anything below it to pry), but happily nothing seems to be more damaged in the removal. It feels like it moves and turns the worm screw to turn the speedo cable...

    Wheel Bearing, Speedometer Problem

    something is missing, damaged or at least stuck. There are no loose parts in my brake plate. The gear that you see is stuck into the brake plate, and gentle nudging is not loosening it. I am concerned that perhaps the speedo gear was damaged when I tightened the wheel with it backwards. Suggestions?

    Wheel Bearing, Speedometer Problem

    I am having a frustrating experience with the front wheel of my 1972 SL100. I had a flat tire a few weeks ago, and when I took the tube out to patch it, found that the failure was at the valve stem, so a new tube was required. Unfortunately, I could not buy one locally, so I decided it was time...

    What kind of battery is this?

    MikeCo: what are your charging voltage in your CT90 with a LiFePO4 battery? The amazon listing you linked suggests that it can accept 7.3V +/- 0.2V, but the rectifier on my CT90 fluctuates a great deal more than this range (as it varies with RPM), running under 6V at idle and over 8V at WOT. I...

    Another Carb post....

    I confirm my understanding that carbs 1978 and later so not have height adjustment on round plastic float. May be worth trying a different gas cap if you can get your hands on one cheap and easy.

    Sparkplug Heat Range

    You are right to observe that I am using referencing the on-board speedo (and not much above 65, but it was not holding WOT and tucked - as I need to do on my CT90), and I will check with a GPS. Regardless, it is noticeably faster than my CT90 which has a speedo reading about 53mph at its...

    dam you rectifier...

    I had a parallel experience of deteriorated wiring on a 1978 CT90, which resulted in strange voltage readings that could not be explained until I started testing for resistance and ran some supplementary wiring to get more volts to where they were needed. I am sure it is not as common as...

    Sparkplug Heat Range

    Thanks OG, that makes sense to me, and how I had figured it to explain the difference between the CT90, which is tuned to be ordinary for durability, and the SL100, which is tuned to get the max power out of the piston. Since I am expecting to be riding at high RPMs (so the motor will be hotter)...

    Sparkplug Heat Range

    I am just adding that the SL100 seems to be at least as happy with the NGK D9EA sparkplug as it was with the D8EA. When I pulled the D8EA it was a little black and greasy, so I thought I should adjust things to be less rich. After a little work (I checked and adjusted valve lash, point gap...

    CT90 Carb and Throttle cable Help!

    Two quick and potentially irrelevant points: I had a good experience with buying a cheap Chinese copy carb to get my 1978 CT90 running when the original carb was leaky and unreliable to start (I could not find a gasket set for the 78-79 carb, but have recently found one at 4into1.com). Second...

    Sparkplug Heat Range

    I am confused because my CT90 is speced for a 7 heat range, while my SL100 is speced for an 8. I would have thought that the SL100 runs hotter (as it is 11.5 HP and definitely has a higher top speed, while the CT90 is only 7 HP, and I assume the vertical cylinder cools more efficiently). I will...

    Sparkplug Heat Range

    I accidentally bought a sparkplug (NGK D9EA) for my 1972 SL100 that is heat range 9 instead of the recommended heat range 8, but not practical to send it back. Since most of my riding is at higher speeds (40-55mph) I was thinking this may not be a problem. From what I read it seems that the...
